Question

What does 1/2 p - 3/8 p =

Answer 1

First, we can factorize p, then we have

`(1)/(2)p-(3)/(8)p=((1)/(2)-(3)/(8))p`

The fraction in parenthesis is equal to

`\begin{gathered} (1)/(2)-(3)/(8)=(1\cdot8-3\cdot2)/(2\cdot8) \\ (1)/(2)-(3)/(8)=(8-6)/(16) \\ (1)/(2)-(3)/(8)=(2)/(16) \\ (1)/(2)-(3)/(8)=(1)/(8) \end{gathered}`

Hence, the answer is

`(1)/(2)p-(3)/(8)p=(1)/(8)p`
